Embodiment
[0020] Embodiment: a kind of large-capacity precipitation measurement measuring cup, such as figure 1 , figure 2 shown. The bottom of the device is a tripod 3, the three legs of the tripod can be telescopically adjusted, and the top of the tripod is provided with a leveling device 2. A cylindrical barrel 1 is placed on the horizontal calibrator 2. The upper part of the barrel 1 is open and provided with a barrel cover 5. The barrel cover 5 is detachable by fastening with the barrel 1. The top of the barrel lid 5 is provided with a handle.
[0021] cylinder structure such as figure 2 , 3 As shown, the cylindrical barrel 1 is made of a transparent material, and a central measuring cup 8 is arranged on the central axis of the barrel. The cup wall of the central measuring cup 8 and the barrel wall of the barrel 1 are divided into 32 equal parts by 32 partitions. sectors, which are the first sector 11, the second sector... to the thirty-second sector 12 in the counterclockwis...

The invention relates to a high-capacity precipitation amount measuring cup. The high-capacity precipitation amount measuring cup solves the problem of large measuring error due to long-time precipitation amount accumulation of the prior art. The high-capacity precipitation amount measuring cup comprises a transparent barrel body with an opening at the upper end, the central axis of the barrel body is provided with a central measuring cup, the part between the central measuring cup wall and the barrel wall of the barrel body is uniformly divided into N sections through N vertical clapboards, each two adjacent sections are divided through the clapboard with a current guide groove at the top, the section N is adjacent to the first section and is separated from the first section through the complete clapboard without the current guide groove, the upper part of the central measuring cup wall is provided with a current guide groove communicated with the first section, and the corresponding barrel body wall of each section is marked with reading scales from the bottom to the lower edge of the corresponding current guide groove. According to the high-capacity precipitation amount measuring cup, the high-capacity measuring cup is divided into a plurality of sections through clapboards, the adjacent sections are used one by one to read the precipitation amount data, and the precipitation amount reading precision is improved based on guaranteeing the high-capacity measuring range; the high-capacity precipitation amount measuring cup is capable of meeting the measuring requirement of large precipitation amount.
Description
technical field [0001] The invention relates to a hydrological measuring device, in particular to a large-capacity precipitation measuring cup for measuring precipitation. Background technique [0002] As the Hydrological Bureau of the Ministry of Water Resources gradually promotes the "unattended, manned" test and management mode in the national rainfall station network, the rainfall calibration gauge of automatic rainfall measurement equipment generally develops from period or daily rainfall to monthly or seasonal rainfall. Meter, the single amount of measurement is greatly increased, and the rainfall is in mm, even up to hundreds of mm. The existing legal rainfall measuring tool is a 10mm measuring cup with a measurement accuracy of 0.1mm. When measuring rainfall, it may be necessary to repeat the measurement dozens of times. The measuring process takes a long time, and it is easy to forget or misremember the number of cups and values. Moreover, the error generated by mu...
